In the era of integrated pest control using biological agents, information on the predatory potentialities of Coccinellids sp. on a banana aphid, Pentalonia nigronervosa, a vector of bunchy top disease virus is important. The aphidophagus coccinellids were continuously observed for two years in the selected fields at Karyavatam of the Kerala State. Total number of aphid colonies and number of colonies having predators were noted. The larval Coccinellids were caught along with some aphids and reared in the laboratory till they become adults in order to facilitate their identification. Seven species of Coccinellidswere found in aphid colony. Of these six species are new record fromKerala and one species is a new record from India. A correlation between the aphid colonies and predator population was traced for 2 years. [ABSTRACT FROM AUTHOR] |
